AKRON, Ohio -- A federal judge has rejected a request for discovery by Michael Gabor, Jimmy Dimora's imprisoned buddy and former driver, in his quest to overturn his 2012 corruption convictions.

U.S. District Judge Sara Lioi in Akron refused the request by Gabor to obtain documents that he contends would prove that people involved in the case committed a "litany of instances of blatant judicial misconduct, prosecutorial misconduct and ineffective assistance of counsel."

In a strongly worded order filed late Monday, Lioi dismissed the contents of Gabor's accusations as "hearsay, conjecture, and wild and unsupported assumptions of wrongdoing." She wrote that he is clearly trying to carry out a "far-flung fishing expedition" and that more discovery is not going to help him.

"After identifying various facially innocent connections that he believes these relatives may have had to other figures in the federal probe, Gabor surmises, without support, that they must have played a key role in the investigation or somehow negatively impacted his case," the judge wrote.

A jury found Gabor, 56, guilty along with Dimora, a former Cuyahoga County commissioner. He was convicted of several crimes, including serving as a bag man for Dimora and former county Auditor Frank Russo and for trying to bribe a judge with $10,000 to fix his divorce case.

He is serving more than 10 years at a federal prison in Elkton. His challenge comes more than a year after the 6th U.S. Circuit Court of Appeals upheld his convictions and the U.S. Supreme Court declined to hear his case.

Prosecutors, after Gabor filed his challenge, asked the judge to inquire whether Gabor is representing himself. In a court filing, they stated that they believed Anthony O. Calabrese III, a fellow inmate and former lawyer serving time for his own corrupt actions, helped him out.

Lioi declined to undertake such an inquiry. While she noted that Gabor did not deny receiving assistance from "a formerly licensed attorney and co-conspirator," she said she is satisfied that Gabor is truly representing himself.

The corruption scandal resulted in convictions of dozens of politicians, public employees and contractors. Dimora, 60, is serving a 28-year prison sentence.
